Shadow Mastiff

Outsider · SM +0 Shadow Mastiff (Enraged Eggplant; answers SRD 3.5)

A black hound the size of a mastiff, hard to make out in anything but full daylight, hunting in packs. The baying is the danger: it gets into the nerve and scatters a group, which is precisely what the pack is waiting for.

Description

Written by Dungeons on Automatic, released under cc_by_4_0

• GCS ancestry draft: gcs/shadow-mastiff.gct
• Source template total: 67 points.
• Library-rebuilt template total: 67 points.
• CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
• Issue #5: 1 special ability construction(s) restored (Bay). 1 save-or-disable construction(s) are scored through the affliction term at the source's stated point cost, or at Binding ST where the source builds the ability as a Binding.
• CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 21, PR 8, CER 29, threat tier standard.
• Conversion baseline reported OR 16, PR 8, CER 24 (tier minor). The reviewed values come from the consumer CER implementation, which rounds damage once after the damage-type multiplier and credits ranged accuracy; the conversion baseline ceilinged the damage base first and ignored range.
• Encounter metadata derived (default): average number appearing 2, wandering weight 3. Encounter metadata derived for 0.2.0 from the reviewed threat tier and creature class (appearing: minor 4 / standard 2 / major 1 / severe 1, forced to 1 for solitary classes — including swarms, which are a single multi-body creature — and raised to 6 for gregarious minor creatures; wandering weight: minor 4 / standard 3 / major 2 / severe 1). The fan-conversion source states no appearing-in-numbers or wandering values, so these are derived, not source mechanics.
• Lair, treasure, and grappling remain unpopulated in 0.2.0 by package policy: the authorized fan-conversion source states no lair, treasure, or grappling values, and review declines to invent them. See review/policy/0.2.0-empty-field-policy.md.
• Description text is original Dungeons on Automatic prose written from this record's own converted statistics and from the project's art direction for the creature. It is not derived from the authorized fan-conversion source, which states no creature descriptions, and not from any SRD. It carries its own authorship and CC BY 4.0 terms in the description field. See review/policy/description-policy.md.
• Review approved by automated-mechanical-review on 2026-07-26 (batch ee-2026-07-26-b5-cer-drift); GCS fidelity check passed, DOA playability check passed.
• The conversion baseline's published ratings disagreed with the consumer CER path; the reviewed ratings come from the consumer implementation and the difference is recorded in conversionNotes.
